That makes perfect sense. But, I'm not so sure it would apply well in rural areas. My public library only has two computers that the public is allowed to use.
Ah, well in that case it would be very easy to ask the librarian to turn off the filtering software for a particular user, then have them turn it back on when the patron is finished.
I was thinking of large libraries where there are 20 terminals and it would be impossible to keep running around turning filtering on and off on each machine.
I understand that most porn filter software blocks valuable medical information about breast cancer, uterine cancer, etc, so it needs to be disabled for certain people, but that is no excuse to reject filtering software outright.
The truth is that Internet porn in libraries draw really frightening and dirty people to the libraries. I have seen some terrible scenes in the San Antonio public library. When I asked a librarian, 'How can you let this go on when there are little kids around?' She said 'Free speech. We can't do anything about it.' Sinister-looking homeless guys fixed to the terminal bringingup image after image of hard-corn porn and kids in sight of it.
When this was revealed in the local paper suddenly they decided it wasn't free speech after all and blocked it.
